Actually, my comment on the reversal is that I think the economics are there, potentially. It's 150,000 barrels per day capacity. As Professor Hughes said, one can actually transport by tanker to the Irving Oil refinery in New Brunswick, or, alternatively, one could do the Portland reversal as well. That could take that capacity. We have to remember, though, that 150,000 barrels per day is really just 10% of what we're talking about—increased production—over the next four or five years from the Bakken and the Alberta-Saskatchewan areas alone. We're really talking about a massive increase in the amount of production that will need to have pipelines to get out, and the number of pipeline projects that are going to be needed as a result.
My comments about the economics had to do with trying to ship going east and going all around North America, through the Panama Canal, to Asia, and whether that's going to be economic. In my view, it won't be economic, although potentially there is another opportunity of perhaps turning the TransCanada pipeline that goes east into an oil pipeline and again taking it by tanker from Montreal and going to the gulf coast. However, the transport costs of doing that, including the marine costs, would be roughly $2.50 more than Keystone XL taking oil from western Canada down to the gulf coast as well.
If you try to go to Asia, you're competing with a number of different sources. In fact, my colleague Michal Moore might want to say a little bit about that because he investigated the pricing and the transport cost issues with respect to that.
